Other similarities:

All four aircraft took off at night. All were running late of schedule. Three aircraft, possibly all, had Exhaust Pressure Ratio EPR anomalies.

Air India Flight 182

"Air India 182 departed Mirabel 1 hour 38 minutes late." "Sunday 23 June 0218 GMT " (2218 EDT or 10:18 PM local time)

Page 166, Air India 182 Indian accident report

"2.4..2.3 Prior to operating the accident flight, ...The flight crew had reported the following three snags:

(ii) EPRL indicator unserviceable in 'Go around' mode."

UAL Flight 811

"Flight 811 departed HNL gate 10 at 0133 Honolulu Standard Time (HST) 3 minutes after the scheduled departure time..." (1:33AM)

Page 1, NTSB Aircraft Accident Report NTSB /AAR-92/02

"The Los Angeles to HNL segment of flight 811, on February 23, 1989, generated four logbook discrepancy entries. All items were cleared by NHL maintenance and none were related to the cargo door."

TWA Flight 800

"8:02 p.m.: After the engine-pressure radio gauge is replaced, the plane, now Flight 800, leaves the gate bound for Paris, with 230 people aboard. " News reports.

" After a 17 minute wait, it reaches the runway and takes off at 20.19. The sun has set shortly beforehand, but visibility at high altitude is still good." News reports.

Comment: The significance of these other similarities is unknown but too often for coincidence. The significance of all having EPR anomalies may be an electrical problem that affects the cargo door motor wiring in the Main Equipment Compartment. The significance of taking off at night running late may imply rushed improper latching of the cargo door in poor visibility. The direct connection of these three similarities to an open cargo door is unproven.
